New pill aims to slash hidden heart risk factor

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Planned or anticipated cardiac, cerebrovascular, or peripheral artery surgery or coronary revascularization or other major surgery after randomization; 3. History of hemorrhagic stroke or other significant bleeding events; 4. History of malignancy in any organ system (except well-treated basal cell carcinoma of the skin); 5. History of diseases that significantly affect lipid levels, such as nephrotic syndrome, severe liver disease, Cushing's syndrome, etc.; 6. Uncontrolled type 1 or type 2 diabetes within 6 months prior to screening (including diabetic ketoacidosis or hyperosmolar hyperglycemic state or HbA1c \> 8.5% at screening); 7. History of acute kidney injury within 12 months prior to screening; 8. Uncontrolled hyperthyroidism or hypothyroidism; 9. Active infection requiring systemic antiviral or antibiotic therapy prior to randomization; 10. New York Heart Association (NYHA) class III-IV heart function or most recent left ventricular ejection fraction (LVEF) \< 30% at screening or prior to randomization; 11. Use of weight-loss medications or surgery leading to weight instability within 2 months prior to screening; 12. Long-term continuous or repeated use of systemic corticosteroids within 3 months prior to screening (excluding local use, such as intra-articular, nasal, inhaled, topical, etc.; long-term continuous means ≥7 days; repeated means cumulative use ≥3 times); 13. Lipoprotein apheresis treatment within 3 months prior to screening, or planned to undergo this treatment during the study; 14. Use of PCSK9 inhibitors within 12 months prior to screening; 15. Allergy to the active ingredient of HRS-5346 or any excipient. Laboratory and Other Tests 16. Uncontrolled hypertension at screening (sitting systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥100 mmHg); 17. Severe renal insufficiency, defined as eGFR \< 30 ml/min/1.73 m² (calculated using the CKD-EPI formula) at screening, or undergoing dialysis; 18.

Participants in any drug or medical device clinical trial within 3 months prior to screening (defined by the participant receiving the trial drug/device treatment), or within 5 half-lives of the trial drug prior to screening, whichever is longer; 25. Participants deemed by the investigator to have poor compliance or any factors that make them unsuitable for this trial, including but not limited to participation posing unacceptable risk to the participant or potentially interfering with study results.
